Once the plugin is installed, you need to go to Site administration > Plugins > Local plugins > Moodle Mobile additional features

There you can choose the "Type of login":

- Via the app: Is the default login, the user must introduce his credentials in the app

- Via a browser window: A new browser instance is open in the mobile device pointing to the login form in the Moodle site. The user must introduce his credentials there. This is the option that must be selected for sites using SSO methods (or for sites that wants to force the user to authenticate in the site, not in the app)

4. Go to Site administration > Users > Define roles, edit the Authenticated user role and allow the capability moodle/webservice:createtoken.

Note: You need to have upgraded the Moodle Mobile app to version 1.4.4.

If you are currently using the Moodle Mobile app, you will need to log out of all your sites in order for the app to detect the new service.

Admin users, please read

This plugin installs a new service in your Moodle installation, the automatic token creation for this type of services is forbidden for admin users. This means that admin users will not be able to use the Mobile app.

This can be solved easily, administrators must create a token manually in Moodle (Plugins > Web Services > Manage tokens) for the local_mobile service.
